... (b) (MIT training 2 star) Let n be an integer greater than one. Show that n4 + 4n is not prime. (hint: there is a magic identity due to Sophie Germain: a4 + 4b4 = (a2 + 2b2 + 2ab)(a2 + 2b2 − 2ab)) (Erin) a) It is pretty easy to see that the answer is 2. Simply do direct long division to obtain the a ...

Elementary arithmetic
Elementary arithmetic is the simplified portion of arithmetic that includes the operations of addition, subtraction, multiplication, and division. It should not be confused with elementary function arithmetic.Elementary arithmetic starts with the natural numbers and the written symbols (digits) that represent them. The process for combining a pair of these numbers with the four basic operations traditionally relies on memorized results for small values of numbers, including the contents of a multiplication table to assist with multiplication and division.Elementary arithmetic also includes fractions and negative numbers, which can be represented on a number line.
